试题分析：be made of和be made from都表示“由……制成”，主语为制成品。 be made of 表示制成成品后，仍可看出原材料是什么。be made from 表示制成的东西完全失去了原材料的外形或特征，或原材料在制作过程中发生化学变化，在成品中已无法辨认。本题中，第一空，纸是由木头制成的，已经看不出原材料，用be made from，第二空，书是由纸制成的，能看出原材料，用be made of，故选B。
考点：be made of和be made from的区别
World Sleep Day, on 21st March, was created to bring attention to the growing number of sleep problems. Sleep is a natural part of human life, but many people in the modern world don’t realize it’s very important. As a result, sleep problems are quite common.
In 2011, scientists at the University of Athens in Greece did a survey of over 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Among the people, 24 percent said that they did not sleep well, 31.6 percent were diagnosed(诊断) with insomnia(失眠). In addition, 30.7 percent of them have visited doctors for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.
The survey found that many people suffer the effects of poor quality sleep, some examples can’t fall asleep and often wake up in the middle of the night. The main reasons of the problems are pressure(压力) from school or work and a fast pace(节奏) of life, but noise pollution and light pollution also affect sleep and cause poor quality sleep. The survey also found that large numbers of people find it hard to sleep at night. The short term effects of this are tiredness and trouble concentrating(专心). If this happens for a long time, the risk of gaining weight and having a heart attack may increase.
There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and wake up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.
Getting a good night's sleep is important for everyone. By following the advice above, you can rest better at night and work better during the day.
